The body mass index (BMI) is a method of assessing whether a person is a healthy weight in relation to their height. Some experts call it the Quetelet index. Using the person's height and weight, BMI indicates whether an individual is underweight, a healthy weight, overweight, or obese. BMI has become the standard method for assessing body weight in many countries across the world. However, there are some instances where using BMI may not be appropriate or accurate.
To calculate a person's body mass index, they will need their height in meters and their body weight in kilograms. Their weight is divided by their height squared to arrive at a numerical value. There are many online tools that can calculate BMI easily.
